Are you sure you're not drawing both a strawman argument and false dichotomy here with respect to near-field communications? While I can't speak with authority on how it'll be implemented, what makes you think that the use of NFC will be without your explicit consent? How is this any different than one taking out a credit card and swiping it at a machine?

Regarding WiFi, Bluetooth, GPS... these options aren't default on my Nexus One. I control when I want to use these features. Barring the cases of strange backdoors and apps secretly grabbing your data, I'm not sure what the issue here is.
